To all whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a

citizen of the United States, residing at Chi-.

cage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hopper-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in hopper cars.

Objects of the invention are to provide a hopper car which has increased load carrying capacity as compared with other cars of similar type and wherein the center of weight of the load is lowered. Gther objects of the invention are to provide a hopper car of the so-called W-type having mechanism for operating the hopper doors, so arranged that the door operating mechanism is positioned beneath the hopper bottom sheets and the mechanism thereby simplified.

In the drawing forming part of this specification, Figure 1 is a part side elevation, part longitudinal section of a hopper car showing my improvements in connection therewith, the end portions of the car being broken away in order to prevent crowding of the drawing. Fig 2 is a part side elevational view, part vertical section showing more particularly the construction and arrangement of one of the hoppers together with its bucket-shaped hopper door and operating mechanism. In this figure, the full lines indicate the position of the parts when the hopper door is closed, and the dotted lines the position of the parts when the hopper door is open. Fig. 3 is a vertical, transverse, sectional view, taken substantially onv the line 33 of Fig. 1, illustrating approximately the section for one-half only of the car. And Fig. 4 is a detailed elevational view, illustrating more particularly the location and arrangement of one of the door operating mechanisms.

In said drawing, the hopper car illustrated is of that type commonly known as the W-type of hopper car, that is, the car is provided with four hoppers, two on each side of the center sill, the hoppers being disposed in pairs on either side of the trans verse center of the car and at the center of the car is formed a transversely extending ridge, the latter comprising ridge sheets 1010. The side walls of the car are designated by the reference 11, the center sills by 12, thejhopper bottom sheets by 13, the inner longitudinally extending side hopper sheets by 14 and the outer longitudinally extending side hopper sheets by 15. As clearly illustrated in Fig. 3,the inner side hopper sheets 14 are ofiset from the center sills 12, in order to accommodate the inner sets of hop per door hinge butts, as hereinafter described, and the outer hopper side'sheets 15 are inclined inwardly toward the longitudinal axis of the car.

Each of the four hoppers of the car is provided with a scoop or bucket-shaped hopper door, designated generally by the reference A. Each of said doors A comprises a main sheet 16 bent to substantially right-angle form, as clearly illustrated in Figs. 1 and 2, the, upper portion 116 of said sheet being bent from the vertical where it is adapted to cooperate with the lower edge of the ridge sheet 10. The ends of the doors A are formed by two substantially triangular shaped plates 17 and 18, the plates 17 and 18 being of substantially right-angle triangle form and flanged so as to overlap the edges of the main door sheet 16, as clearly indi cated at 117 and 118 in Fig. 3. In this manner, the bucket-shaped doors may be made at comparatively small expense, while at the same time providing the necessary strength.

Each of the doors A is adapted to swing about an axis extending through the side sheets of the corresponding hopper and at a point above the lower edge of the adjacent ridge sheet 10. To accomplish this, each hopperdoor A is provided at its inner side with a hinge bracket 19, which is pivotally supported in the space between the center sill and hopper side sheet 14, as indicated at 20. The hinge bracket 19 may be conveniently formed of-a plate of suitable shape with the edges flanged to provide the requisite strength. On the outer side, each door A is provided with another hinge bracket 21 of a shape shown in the drawing and having reinforcing flanged edges, as indicated at 121121, said bracket being pivotally supported between the outer hopper side. sheet and a depending bracket 22, as indicated at 23.

By forming the hopper doors A in the manner shown and described, I am enabled a position outside of said outer hopper side sheet.

4. In a hopper car having four hoppers arranged in pairs on opposite sides of the center sill, said car having a transverse cen tral ridge, the combination With pivoted hopper doors for said hoppers, and mechanism for operating said doors, said mechanism including for each transverse pair of hopper doors, a transversely extending shaft disposed beneath the hopper bottbm sheets, lever arms on said shaft also disposed beneath the hopper bottom sheets, and link connections from said lever arms to the hopper doors, said shaft being rotatable in a direction to swing the lever arms away from the hopperbottom sheets when the hopper doors are being opened.

In a hopper car having four hoppers arranged in pairs on opposite sides of the center sill, each hopper being formed by an inclined hopper bottom sheet, an innerlongitndinally extending side hopper sheet spaced from the center sill of the ear, and an outer longitudinally extending hopper side sheet, the latter being inclined from the side Wall of the car toward the center sill, the combination with a bucket-shaped hopper door for each of said hoppers, means for pivotally supporting each of said hopper doors, each of said means comprising flanged plate hinge butts pivotally mounted between the inner hopper side sheet and the center sill and between the outer hopper side sheet and the side Wall of the car, of mechanism for 40 operating said doors, said mechanism including transversely extending shafts disposed beneath the hopper bottom sheets, lever arms on said shafts also disposed beneath the hopper bottom sheets, and link i connections from said lever arms to the hopper doors,

In Witness that I claim the foregoing I have hereunto subscribed my name this 20th. day of Dec, 1917.
